8 Claims, 5 Drawing Figures MOLD FOR BUNS WHICH HAVE CENTRALLY-LOCATED RECESSES This invention related to improvements in molds for buns. More particularly, this invention relates to improvements in molds which can be used to form buns that have centrally-located recesses therein.

It is, therefore, an object of the present invention to provide a mold which can be used to form buns that have centrally-located recesses therein.

The, present invention provides a mold which can be used to form a bun that has a deep, centrally-located recess therein which is defined by a continuous absorbent wall, so that bun will be able to confine semi-liquid as well as solid edibles. Such a bun is very useful and desirable in holding a frankfurter on which chili,- semiliquid sauces, or runny condiments have been placed. The continuous wall, which defines the deep, centrally-located recess will hold the chili, sauce or condiments in immediate proximity to the frankfurter, and also will keep that Chili, sauce or condiments from dripping onto the ground. In addition, that continuous wall is sufficiently absorbent to absorb and hold enough of the moisture from the chili, sauce or condiments to enable one end of the bun to be progressively eaten away, as one end of the frankfurter is progressively eaten away, without permitting that chili, sauce or condiments to drip onto the ground. It is, therefore, an object of the present invention to provide a bun which has a deep, centrally-located recess therein defined by a continuous absorbent wall.

The centrally-recessed bun provided by the present invention is formed on a mold which has a support of heat-resistant material, a surface which is displaced in the upward direction from that support, a recess of semi-circular cross section which is displaced in the downward direction from that support and which extends around and extends laterally outwardly relative to that surface, and an inclined wall which extends upwardly from the inner periphery of that recess to the periphery of that surface.

Other and further objects and advantages of the present invention should become apparent from an examination of the drawing and accompanying description.

In the drawing and accompanying description, two preferred embodiments of the present invention are FIG. 5 is a sectional view, on the scale of FIG. 2, through a mold which is generally similar to the mold of FIG. 1 but which produces a circular bun rather than an elongated bun.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1-4, the numeral 10 generally de.- notes one preferred embodiment of mold that is made in accordance with the principles and teachings of the present invention. That mold is made from metal which is resistant to heat and to corrosion; andthat mold can be made from stiff foil, can be made-from a sheet of metal as a stamping, or can be made as a casting. The mold 10 is shown as a planar support which has a stiffened edge 12 that extends around the periphery thereof. If the mold 10 is made from a sufficientlythick and stiff sheet of metal, or if it is made as a casting, the stiffened edge 12 of the planar support of that mold couldv be omitted.

The numeral 14 denotes an elongated, flat surface which has parallel sides and rounded ends, and that surface is displaced upwardly above thelevel of the planar support of the mold l0. The numeral l6 denotes a recess which extends downwardly below the level of the planar support of the mold l0; and that recess is semicircular in cross section. As indicated particularly by FIG. 1, the recess 16 is continuous and it defines two elongated straight sides, and the ends of those sides are joined by semi-circular portions. As a result, the recess 16 extends around and encloses the surface 14; and that recess also extends laterally outwardly relative to that surface. The outer periphery of the recess 16 merges smoothly into the planar support of the mold 10. A continuous wall l8v inclines upardly from the inner periphery of the recess 16 to the periphery of the surface 14; and that wall interconnects-that recess and that surface. The wall 18 merges into the surface 14 by means of a smoothly rounded joint; and that wall merges into, the inner periphery of the recess 16 in a smooth and uninterrupted manner.

The mold 10 is shown as being provided with a number of surfaces 14, a number of recesses 16, and a number of inclined walls 18; and any desired numbers of shown and described but it is to be understood that the drawing and accompanying description are for the purpose of illustration only and do not limit the invention and that the invention will be defined by the appended claims. I

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a plan view of a portion of one preferred embodiment of mold that is made in accordance with the principles and teachings of the present invention,

FIG. 2 is a sectional view, on a larger scale, through a portion of the mold shown in FIG. 1, and it is taken along the plane indicated by the line 2-2 in FIG. 1,

FIG. 3 is a perspective view, on a scale smaller than that of FIG. 1, of a bun which can be made fromthe mold of FIG. 1,

FIG. 4 is a sectional view, on the scale of FIG. 2, of a portion of the mold shown in FIG. 1, and it is taken along the plane indicated by the line 4-4 in FIG. 2, and

those surfaces, recesses and walls can be provided for that mold. The greater the number of surfaces 14, recesses 16 and inclined walls 18, the thicker and stiffer the mold should be to enable that mold to have the requiredv strength and sturdiness for repeated usage.

The mold 10 will be formed so that exposed area of the recess 16, the exposed area of the inclined wall 18 and the exposed area of the surface 14 will be very smooth and will readily release any dough which has been baked while in engagement with them. That mold also will be formed so. it is free of any dihedral angles which could tend to cause baked dough to resist rea-' sonable efforts to free it from that mold.

The numeral 20 in FIG. 4 denotes a layer of yeastraised dough after that layer has been rolled flat, has been cut so it has a generally-oblong configuration, and has been laid on the mold 10 with the central portion thereof resting nicely on the exposed area of the surface 14 and with the edge thereof resting nicely within the recess 16 and with the intermediate portions thereof resting nicely against the exposed area of the inclined wall 18. Because the exposed areas of the surface 14, ofthe recess 16 and of the inclined wall 18 do not subtend any abrupt dihedral angles, the layer 20 of yeast-raised dough can be laid on those areas without tending to tear that layer or to cause that layer to have any excessively-thick portions. The numeral 22 in FIG. 2 denotes the layer 20 of yeast-raised dough after that layer has been given time to proof itself; and, in its proofed state, the layer 22 is thicker, and the edge thereof largely fills the recess 16 and assumes the semicircular cross section of that recess. The proofed layer 22 of yeast-raised dough will receive full support from the surface 14, from recess 16, and from inclined wall 18 during and subsequent to the proofing thereof.

The numeral 24 in FIG. 3 generally denotes a bun which was baked while resting on the mold l and which was subsequently freed from that mold and inverted. That bun has a smoothly-rounded upper edge 26 of semi-circular cross section, has a continuous upwardly and outwardly inclined wall, and has an essentially flat bottom which coacts with that wall to define an elongated, deep, centrally-located recess 28; That recess is long enough to accommodate frankfurters of commercially-available length; and that recess is wide enough and deep enough to hold appreciable quantities of chili, sauce or condiments in enagement with that frankfurter.

The mold permits the bun 24 to be proofed and then baked without any need of a female-type mold, and thus avoids the sticking which frequently is experienced when a female-type mold is used with a maletype mold in the baking of dough. Consequently, that bun can easily and quickly be separated from the mold 10 without any part of that bun being broken or torn merely by inverting that mold and striking one edge thereof. Further, because the outer areas of the bottom and of the wall of the bun 24 will be exposed to air during the proofing and baking of that bun, those areas will have a desirably uniform color, and, more importantly, will have a low degree of porosity. In contrast, the inner surfaces of the bottom and of the wall of the bun 24, and the convex upper edge of that bun, will proof and will be baked while in contact with the metal surfaces of the mold 10; and hence those inner surfaces and that upper edge will have a higher degree of porosity. That higher degree of porosity will be desirable because it will enable the bun'24 to absorb enough of the moisture from the chili, the sauce or condiments on the frankfurter to enable the consumer to eat away one end of that bun without permitting the chili, sauce or condiments to run out. Further, the high degree of porosity of the convex upper edge of the bun 24 is desirable; because it will enable that convex upper edge to absorb moisture from any chili, sauce or condiments which may be spilled onto that convex upper edge as the consumer or server applies chili, sauce or condiments to the frankfurter Within the recess 28. In absorbing that moisture, that convex upper edge will tend to keep that chili, sauce or condiments from falling onto the ground. The convex nature of the upper edge of the bun 24 is desirable because it enables at least one-half of that upper edge to act in funnel-like fashion to guide any chili, sauce or condiments applied thereto into the recess 28 within that bun. Further, the convex nature of the upper edge of the bun 24 is desirable because it will keep that upper edge from irritating or chafing even the tenderest of lips and mouths.

In the preferred embodiment shown by FIGS. 1, 2 and 4, the surface 14 is displaced approximately thirteen-sixteenths of an inch above the level of the planar support of the mold 10, and the lowermost portion of the recess 16 is displaced approximately one-quarter of an inch below the level of that planar support. Further, the maximum longitudinal dimension of the surface 14 is approximately 5 /2 inches, the width of that surface is approximately 1 inch, the inner periphery of the recess 16 is displaced laterally outwardly of the periphery of the surface 14 by approximately one quarter of an inch, and the width of that recess is approximately one half of an inch. However, if desired, any or all of those dimensions can be varied to correspond to the dimensions of frankfurters of different size.

Referring particularly to FIG. 5,'the numeral 32 generally denotes a mold which can be used in the forming and baking of a centrally-recessed bun for hamburgers. That mold is made from metal which is resistant to heat and to corrosion; and that mold can be made from stiff foil, can be made from a sheet of metal as a stamping, or can be made as a casting. The mold 32 is shown as a planar support which has a stiffened edge 34 that extends around the periphery thereof. If the mold 32 is made from a sufficiently thick and stiff sheet of metal, or if it is made as a casting,the stiffened edge 34 of the planar support of that mold could be omitted.

The numeral 36 denotes a surface which is displaced upwardly above the level of the planar support of the mold 32; and that surface will be circular in plan to correspond to the circular configuration of a hamburger. The numeral 38 denotes a recess which depends downwardly below the level of the planar support of the mold 32; and that recess is semi-circular in cross section. The recess 38 is continuous, it is concentric with thesurface 36, it extends laterally outwardly relative to that surface, and it completely surrounds that surface. A continuous wall 39 inclines upwardly from the inner periphery of the recess 38 to the periphery of the surface 36; and that wall interconnects that recess and that surface. The wall 39, which is frusto-conical in configuration, merges into the surface 36 by means of a smoothly rounded joint; and that wall merges into the inner periphery of the recess 38 in a smooth and uninterrupted manner.

The mold 32 differs primarily from the mold 10 of FIGS. 1, 2 and 4 in that the surface 36 of the mold 32 is circular in plan whereas the surface 14 of the mold 10 is elongated in plan, and in that the recess 38 of the mold 32 is circular in plan whereas the recess 16 of the mold10 has elongated parallel sides. The mold 32 will be provided with a number of surfaces 36, a number of recesses 38, and a number of inclined walls 39, not shown. The numeral 40 denotes a layer of yeast-raised dough which has been laid on the mold 32 and then permitted to proof. Initially, that layer had a cross section which was generally comparable to that of the layer 20 shown in FIG. 4; and, at that time, the layer 40 was thinner than shown by FIG. 5, and its edge only partially filled the recess 38. As it proofed, the layer 40 assumed the configuration shown by FIG. 5, and hence it developed a cross section which is similar to that of the layer 22 in FIG. 2.

The mold 32 permits the layer 40, and the resulting bun, to be proofed and then baked without any need of a female-type mold, and thus avoids the sticking which frequently is experienced when a female-type mold is used with a male-type mold in baking dough. Consequently, that bun can easily and quickly be separated from the mold 32 without any part of that bun being broken or torn merely by inverting that mold and striking one edge thereof. Further, because the outer areas of the bottom and of the wall of the resulting bun will be exposed to air during the proofing and the baking of that bun, those areas will have a desirably uniform color and, more importantly, will have a low degree of porosity. In contrast, the inner surfaces of the resulting bun, and the convex upper edge of that bun, will proof and will be baked while in contact with the metal surfaces of the mold 32; and hence those inner surfaces and that upper edge will have a higher degree of porosity. That higher degreee of porosity will be desirable because it will enable the resulting bun to absorb enough of the moisture from the chili, the sauce or condiments on the hamburger to enable the consumer to eat away one side of that resulting bun without permitting the chili, sauce, or condiments to run out. Further, the high degree of porosity of the convex upper edge of the resulting bun is desirable; because it will enable that convex upper edge to absorb moisture from any chili, sauce or condiments which may be spilled onto that convex upper edge as the consumer or server applies chili, sauce or condiments to the hamburger within the centrally-located recess in that resulting bun. In absorbing that moisture, that convex upper edge will tend to keep that chili, sauce or condiments from falling onto the ground. The convex nature of the upper edge of the bun is desirable because it enables at least one-half of that upper edge to act in funnel-like fashion to guide any chili, sauce or condiments applied thereto into the centrally-located recess within the resulting bun. Further, the convex nature of the upper edge of that bun is desirable because it will keep that upper edge from irritating or chafing even the tenderest of lips and mouths.

' In the preferred embodiment shown by FIG. 5, the surface 36 is displaced approximately three-eighths of an inch above the level of the planar support of the mold 32, and the lowermost portion of the recess 38 is displaced approximately one-quarter of an inch below the level of that planar support. Further, the diameter of the surface 36 is approximately three'inches, the inner periphery of the recess 38 is displaced laterally outwardly of the periphery of the surface 36 by approximately one quarter of an inch, and the width of that recess is approximately one-half of an inch. However, if desired, any or all of those dimensions can be varied to correspond to the dimensions of hamburgers of different size.

It will be noted that no part of the dough which is applied to either of the molds 10 or 32 is deposited within a dihedral angle defined by walls; and hence neither of those molds will experience the sticking of the baked buns which is experienced by molds which have dihedral angles and which are used to proof and bake buns. Further, it will be noted that as the yeast-raised dough is applied to either of the molds 10 and 32, that dough is not bent over sharp edges, and it need not be stretched to fit exact dimensions. Instead, that dough is permitted to drape over. flat or gently-rounded surfaces, and the edges of that dough are permitted to extend into smoothly rounded,- concave recesses. Moreover, it should be noted that as the yeast-raised dough is proofed on the molds l0 and 32, it is not confined to fixed and arbitrary dimensions and, instead, can assume the dimensions which the proofing nature of the dough requires.

Whereas the drawing and accompanying description have shown and described two preferred embodiments of the present invention, it should be apparent to those skilled in the art that various changes may be made in the form of the invention without affecting the scope thereof.
